Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The behaviour, attitudes and acceptability of patients, healthcare professionals and managers regarding the use of Direct oral Penicillin Challenge (DPC) in ‘low risk’ patients, assessed using 1-1 interviews and focus groups between 6 – 18 months of the study | — |
Secondary
| Measure | Time frame |
|---|---|
| Measured at a single timepoint: 1. The proportion of ‘low risk’ patients with a PenA label who would be eligible for a DPC, measured by applying risk stratification criteria (4-18 months) 2. The proportion of ‘low risk’ patients who would be willing and complete a DPC, measured by the number of ‘low risk’ patients who give informed consent (4-18 months) 3. The practical aspects of implementing this de-labelling programme in secondary care by investigating factors such as organisational context, treatment pathway, protocol implementation, time taken and resources (based on qualitative and quantitative methods applied in the study) 4. The potential cost-effectiveness of this service model, calculated using health economics methods comparing the cost of standard care provided to PenA patients compared to the new proposed service model between 17-22 months | — |
